Modified Bonding Steel Adhesive What is the function of Bonding Steel Adhesive?
High strength, especially the bonding strength of steel - steel and steel - concrete;
Good anti-aging and medium resistance (acid, alkali, water) performance;
Has good toughness and impact resistance;
Curing at room temperature, with low shrinkage after hardening;
The proportion of ingredients is wide, and the curing time can be adjusted appropriately according to the needs of users;
Does not contain volatile solutions, is safe and convenient for construction;
Appearance Component A: Milky red pasty liquid. ***Proportion (weight ratio) Component A: Component B = 3:1
Component B: Brownish red pasty liquid. Mixed density 1.2 ± 0.1g/c
Colloidal properties Tensile strength, Mpa ≥ 30 Tensile elastic modulus Mpa ≥ 3.0 × 10³
Elongation rate % ≥ 1.3 Flexural strength Mpa ≥ 45, and brittle (fragmented) failure
Compressive strength Mpa ≥ 65
Bonding ability Steel - steel tensile shear strength, Mpa ≥ 15 Steel - steel uneven tensile strength, KN/m ≥ 16
Steel - steel bonding tensile strength, Mpa ≥ 33 Positive tensile bonding strength with concrete, Mpa ≥ 2.5 and cohesive failure in concrete
Anti-aging performance Artificial 2000h anti-humid heat aging (steel - steel shear strength reduction rate) ≤ 10%
Anti-aging performance (5 - 45) Operating time/minutes 20 - 90 Curing time/days 3 - 7
Surface treatment of concrete and steel plate → Fastening the steel plate and welding → Sealing holes and surrounding gaps → Preparation of grouting adhesive → Pressure grouting → Pressure fixation → Curing and maintenance
Clear the floating dust, dirt, oil stains and dirt on the bonding surface of the old concrete; if there are honeycombs and cracks on the surface, they should be repaired and leveled.
After grinding, the structural body is exposed and wiped clean, and the bonding surface of the steel plate is clamped and derusted; after grinding, the bonding surface should show a metallic luster and be wiped clean.
The adhesive should be mixed strictly according to the proportion of weighing, and fully stirred without sediment, color difference. The container should be clean, and there should be no dust, moisture and pomelo mixed in. Mechanical stirring must be used to ensure that the components A and B are evenly mixed.
The prepared adhesive should be used immediately. When applying the adhesive, for horizontal bonding, it should be thicker in the middle and thinner at the edges, and for vertical bonding, it should be thicker at the top and thinner at the bottom, with no missed application;
After the steel plate is pasted, it should be pressurized and fixed until the adhesive is extruded from the periphery of the steel plate at the same time;
The steel plate should not be partially depressurized during pressurization. After 24 hours, the pressure can be released, and it can be used after 3 days;
After the pasting and reinforcement are cured and the pressure is released, anti-rust and anti-corrosion treatment should be done well
After the steel plate is bonded and cured, the compactness should be tested. A small hammer can be used to gently strike the steel plate to determine the effective area from the impact, and the compactness should meet the relevant regulations.
Packaging: 15kg/bucket for Component A; 5kg/bucket for Component B
Storage period: Half a year (Stored at a temperature below 30℃, in a cool place)
